TURBINE Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that I, NEWTON MoKEE, a citizen of the United States, and amember of the National Home for Disabled Volunteer Soldiers atMilwaukee, in the county of Milwaukee and State of Wisconsin, haveinvented a new and useful Improvement in Turbines, of which thefollowing is a specification.

My invention relates to turbines in general and more particularly to theclass of turbines adapted to be driven by steam pressure.

The principal object of my invention is to provide in a turbine meansfor utilizing and reutilizing the power-to be had from the velocity andexpansiveness of steam to the greatest advantage.

Referring to the drawings: Figure 1 is a plan view with parts brokenaway; Fig. 2 is a cross sectional view on lines 22 of Fig. 1; Fig. 3 isa cross sectional view on lines 3-3 of Fig. 1; Fig. 4 is a crosssectional view on lines 44 of Fig. 1 showing the inside of the cylinderend and Fig. 5 is a cross sectional view on lines 55 of Fig. 1.

Referring by letters to the figures: A has reference to a stationarycylinder casing provided with a main shaft A extending through itscenter axially, which shaft has bearings at different points in asuitable frame A which in turn rests on a base A Leading from the steamsupply I provide inlet ports A adapted to supply means of power to theturbine. Said mlet ports are arranged to project steam against blades Bon a tangent and to give power to the turbine through the velocity ofthe steam. Blades B have as a supporting frame work a distance iece hubB the combination of the two forming an initial running wheel which isadapted to be firmly keyed to shaft A Steam projected on a tangentagainst blades B moves centrifugally against a lap ring I) and ispermitted to expand in recesses 01, and by exerting a pressure againstlugs a will exert an expansive force against blades B. The steam fromrecesses a reacts until it reaches the peripheral trailing buckets ormain portion steam chambers formed in the space between said blades Bwhich contain the steam ports 6 of the initial running wheel throughwhich the steam passes into steam ports 5 of the twin bucketed orauxiliary, wheels B and escapes centrifugally through peripherialtrailing buckets 6 arranged on the periphery of said wheels B intodeflector cups 5 arranged on the inside of casing A and encirclingcachof said auxiliary or twin bucketed wheels. From deflector cups b thesteam finds means of escape in a centripetal direction through steamports 6 of wheels B and again pro-i jects itself into reaction bucketsformed in the space between deflectors If arranged on the inside of theend walls of easing A and outwardly from ring Z). From said cups thesteam again reacts into buckets formed in the space between ribs barranged on the outside wall of the twin bucketed wheels B from whichbuckets the steam again-reacts against a plurality of stationarysections 5 located on the inside of the end wall of casing A andinwardly from ring t from which point it is permitted to freely escapeto exhaust port I)". Secured t0 auxiliary wheels B I provide guide ringsA which serve to retard the escape of steam from the peripheral trailingbuckets of wheels B At both ends of cylinder casing A I have providedstuffing boxes a adapted to secure steam tight oints.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. A turbine comprising twin bucketed wheels separated upon a shaft by adistance piece hub, blades for said hub forming main portion steamchambers and means arranged whereby the steam is passed centrifugallyfrom said steam chambers to the buckets of said wheels.

2. A turbine comprising twin bucketed wheels separated upon a shaft by adistance piece hub carrying blades, a lap ring encircling said blades,lugs and recesses arranged on the inner face of said ring and steamports adapted to pass steam centrifugally from the steam chambers formedbetween said blades to the buckets of said wheels.

3. A turbine comprising a bucketed wheel, a distance piece hub securedto said wheel upon a shaft, blades for said hub, the distance betweenwhich forming main portion steam chambers and means provided for theescape of steam centrifugally from said steam chambers to the buckets ofsaid wheel.

4. A turbine comprising twin bucketed wheels, a distance piece hubseparating said wheels upon a shaft, blades for said hub forming mainportion steam chambers, steam ports in the steam sides of said wheelsadapted to conduct steam centrifugally therein and steam ports ontheoutside of said wheels adapted to conduct steam centripetally therein.

LL,- 5. A turbine comprising twin bucketed wheels, a distance piece hubseparatin said wheels upon a shaft, blades for sairl hub forming mainportion steam chambers, steam ports in the steam sides of said wheels, acasing for said turbine, deflector cups arranged in said casing, steamports on the outside of said wheels adapted to conduct steamcentripetally therein, and deflectors arranger .on the inside of the endof said casing.

6. A turbine comprising twin bucketed wheels, a distance piece hubseparating said wheels upon a shaft, blades for said hub forming mainportion steam chambers, means for conducting steam centrifugally throughsaid wheels, a casing for said turbines, deflector cups arranged in saidcasing, means for conducting steam centripetally through said wheels,deflectors arranged on the inside of the end of said casing and a guidering adapted to retard the escape of steam from said buckets.

7. A turbine comprising twin bucketed wheels, a distance piece hubseparating said wheels upon a shaft, blades extending on a tangent fromthe periphery of said hub the distance between which forming main ortionsteam chambers, steam ports provided in the steam sides of said wheeladapted to convey steam centrifugally therein, a casing for saidturbine, deflector on s ada ted to receive steam from said whee s andeflect it back again, steam ports on the outside of said wheels ada tedto conduct steam centripetally in sai wheels, deflectors and sta tionarysections arranged on the inside of the end of said casing, ribs on theoutside of said wheels and an exhaust port therefor.

8. A turbine comprising an initial running wheel and twin bucketedwheels each provided with trailing peripheral buckets, and each twinbucketed wheel having steam ports arranged for outward delivery throughthe buckets, a stationary member rovided with a set of deflector cupsencircling each of the twin bucketed wheels, said initial running wheelbeing provided with steam ports leading to the steam ports of the twinbucketed wheels, the end walls of said casing being provided withreaction buckets and the twin bucketed wheels being provided withinwardly and laterally extending steam ports arranged to discharge intosaid end wall buckets.

9. A turbine comprisin an initial running wheel and twin bucketed wheelseach provided with trailing peri heral buckets and each twin bucketed wieel having steam ports arranged for outward delivery through thebuckets, a stationary member provided with a set of deflector cu sencircling each of the twin bucketed whee s, said initial runnin wheelbeing provided with steam ports leading to the ports of the twinbucketed wheels, the opposing end walls of said casing and walls of thetwin bucketed wheels being provided with buckets and said twin bucketedwheels having outlet steam ports leading radially inward from theperipheral buckets and laterally outward between the side buckets,together with exhaust ports leading through the end wall of the casing.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
